Study in bean segregation population (F2 Generation)

This investigation was conducted for identifying (evaluation of) superior bean plant in khomein bean research station for one year The khomein basis of the single plant selection was, yield, marketing, plant form disease under natural epidemic tolerance and other desired characters. Twenty eight F2s derived form previous crosses of different type which of beans (navy bean, kidney bean and cranberry) separately were cultivated. Depending on the number of seeds F2s sown in 6m rows spaced 50cm, and the in /row plant spacing was 20 cm. To confirm the F2 crosses and also for better evaluation the parents were sown in two rows before and after F2s, while one row spaced between them. To minimize the effect of environment (non - genetic effects) on the quantitative characters, the yield of all selected plants were harvested individually, threshed and stored separately. plants were Harvested. For adaptation and better selection strategy it is recommended the seeds of selected plants to be sown at least in two bean regions. The desired single plants should be selected based on the identified goals for achieving better pure Lines in the regions and finally the variety for the regions and country will be derived introduced.
